The emotional nature of a human being is extremely deep, often infinitely so. It is not uncommon for someone to become overwhelmed when he experiences the full range of his feelings that a negative situation or trauma elicits. This often happens when one is angry.
Imagine an empty glass on a table. Someone comes and fills the glass half-full with water. A little while later, someone else enters the room and fills the glass to the brim. If a third person comes along and adds more water, then the water will simply overflow, since there is no room left in the glass.
Take a look at a typical day for a man named George: He gets up in the morning bursting with vigor and full of happy expectations. When he enters the kitchen to eat breakfast, his wife is busy with the baby and forgets to say good morning. He feels slightly put out, but, “No big deal; that’s life,” he tells himself, and he puts it out of his mind. He may think he just forgot about it, but in reality, that subtle insult is stored in some inner niche, filling up his emotional “glass” to a certain degree.
